EA6900 Internet Connection Issue - Desktop connected via ethernet cable

Question

Hi there,
I have an HP p6837c, 64-bit OS with Windows 7 Home Premium. It is directly connected to the EA6900 via ethernet cable. My internet connection constantly drops (as in variably every 5 seconds to 5 minutes) then re-establishes itself. I have no internet connection issues when directly connected to the modem. All of the wirelss devices that are connected via the EA6900 are working without any issue. My husband's laptop, which has Windows 8.1, functions with no problem when directly connected to the EA6900 via ethernet cable. We've tried swapping out the cable. We've tried adjusting the MTUs per Support's suggestion. Nothing has solved the issue
Any thoughts on what the issues might be? Settings? The version of Windows? Any help would be much appreciated!

Internet Service Provider and Modem Configurations
What ISP Service do you have? Cable or DSL?
What ISP Modem Mfr. and model # do you have?
Is ISP Modem/Service using Dynamic or Static WAN IP addressing?
What ISP Modem service link speeds UP and Down do you have?
Check cable between Modem and Router and PC, swap out to be sure. Link>http://en.wikipedia.org/wiki/CAT6 is recommended.
Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask.
I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.
Router and Wired Configurations
Setup DHCP reserved IP addresses for all devices ON the router. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting and maintain consistency for applications that need to connect as well as mapped drives.
Ensure devices are set to auto obtain an IP address.
If http://en.wikipedia.org/wiki/Ipv6 is an option on the router, select Local Connection Only.
PC 3rd Party Security Software Configurations
Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.
